If no position is explicitely defined, the window manager will decide
where to display a new window.

Personally I prefer the first (and in some cases the last) option.
Forcing my app to appear in the upper left corner or center it on the
desktop imho does not make much sense, the users will resize and
reposition them as they want anyway. If any explicit geometry
specification, then I'd tend to restore the last size and position of the
app window, because there is a chance that it comes close to what they
